BACKGROUND: Laser resurfacing of cutaneous scars, rhytides, and photodamaged skin has become very popular. Pulsed erbium:YAG laser resurfacing has recently come into favor for the treatment of pitted acne scars. OBJECTIVE: This study was designed to investigate the efficacy and safety of pulsed erbium:YAG laser in cutaneous resurfacing of pitted acne scars. METHODS: 100 patients with pitted acne scars were enrolled in this study. All patients were treated by means of a pulsed erbium:YAG laser with a 2 mm handpiece at the setting of 500 to 1000mJ/pulse and fluences used varied between 5-15J/cm2. Photographs of the face were obtained at baseline and 2 week postoperatively. Two weeks after treatment, postoperative care such as applying hydroquinone 4% and tretinoin 0.05% was recommended for 2 to 4 weeks. RESULTS: Out of 100 patients, 20% of patients showed an excellent response, 50% a good response, 21% a fair response and 9% a poor response. After 6 months, erythema had developed in two patients and and three patients had developed postinflammatory hyperpigmentation, hypopigmentation and delayed contact dermatitis. CONCLUSION: Treatment with pulsed erbium:YAG laser shows high efficacy and low morbidity in pitted acne scar resurfacing.

PURPOSE: The purpose of this study was to investigate factors associated with suspicious developmental delay in infants and early childhood. METHODS: Participants were 133 infants, aged from birth to 6 years old and their mothers, who were being seen at 16 Public health centers in B city. Korean Denver II was used to test infant development. chi2-test, Fisher's exact test and multiple logistic regression were used with SPSS 19.0 to analyze data. RESULTS: Of participant infants, 7.5% were below the 3rd percentile for the weight percentile, 8.4% is a weight curve that crosses more than 2 percentile lines on the growth charts after previous achievement, and 9.8% had suspicious developmental delay according to Korean Denver II. Further the predictive factors related to suspicious development delay in the children were decrease of weight percentile (Odds Ratio [OR]=6.69, Confidence Interval [CI])=1.22-36.45), low economic state (OR=6.26, CI=1.50-26.00), and developmental delay perceived by their mothers (OR=4.99, CI=1.24-20.06). CONCLUSION: It is necessary to build a government level system to follow management of development of infants and children from the time of birth. Especially, it is necessary to develop a program for children in low income families.

Trichoblastoma is a rare benign neoplasm that arises in the follicular germinative cells. The terminology and histopathological definition of this tumor is both complex and confusing. Trichoblastoma occurs only on the hair bearing areas such as the scalp, face and pelvic area with varying degrees in size. We describe a case of trichoblastoma occurring as a nodule on the nose. The tumor was composed of numerous lobules of basaloid epithelial cell nests with distinct peripheral palisading of nucleoli that were clearly demarcated from the stroma.

Syndromal acanthosis nigricans is associated with cellular resistance to the action of insulin and other endocrinopathies. In the insulin resistant state, increased insulin binds to the receptors of insulin-like growth factors (IGFs). IGFs are growth prompting peptides, which act as direct mitogens on cells containing the receptors. Through these actions, increased cellular growth and metabolism cause the skin lesions of acanthosis nigricans. Hyperandrogenism is also found in syndromal acanthosis nigricans patients. When associated with insulin resistance, these states are proportionally related. Increased insulin prompts the synthesis of androgen and conversely, increased androgen elevates the insulin resistance. We present three cases of syndromal acanthosis nigricans with hyperpigmented skin lesions and obesity. Laboratory findings demonstrated normal fasting blood suga levels with increased insulin and C-peptide levels and decreased insulin receptors. The oral glucose tolerance test was normal. We suggest that these patients were in an insulin resistant state. Skin biopsies from the axilla in all three cases showed hyperkeratosis, irregular acanthosis and upward projection of dermal papillae as finger like fashion. Thus all three cases represent syndromal acanthosis nigricans associated with an insulin resistant state based on clinical, histopathological, and laboratory findings. The three patients were treated with dietary control.

OBJECTIVE: The purpose of this study is to investigate the prognostic factors and appropriate treatment in patients with intracerebral hemorrhage secondary to ruptured middle cerebral artery(MCA) aneurysms. METHODS: Among 120 cases with ruptured MCA aneurysms during last 9 years from 1993 to 2002, 85 cases was analyzed according to hematoma distribution. All cases were included in one of three groups Group A(15 cases) having an intraparenchymal hematoma(IPH) larger than 5cc with or without subarachnoid hemorrhage(SAH). Group B(25 cases) having an intrasylvian hematoma(ISH) with or without SAH. Group C(45 cases) having a diffuse SAH without localized hematoma. Prognosis was evaluated postoperatively by applying Glasgow Outcome Scale(GOS) at discharge. RESULTS: In Group A, hypertension and Hunt-Hess(H-H) grade on admission, hematoma volume larger than 15cc and postoperative edema were corrleated with poor outcome. In Group B, old age, postoperative edema and delayed ischemic neurologic deficit(DIND) were related to poor outcome. Group C revealed better consciousness on admission and favourable outcome than Group A and B. CONCLUSION: We suggest that therapeutic consideration in Group A is focused on postoperative edema after early surgical intervention and in Group B is focused on postoperative edema with DIND after removal of residual clot in sylvian fisssure as much as possible by irrigation and suction.

Heterotopic gastric mucosa in the upper esophagus is frequently found during endoscopic examination. Although most patients with heterotopic gastric mucosa of the upper esophagus, referred as inlet patch, are asymptomatic, symptomatic patients with complications resulting from this ectopic mucosa have also been reported. Acid secretion by the inlet patch has been suggested in some reports. We report a case of heterotopic gastric mucosa in the upper esophagus, with secretion of acid, demonstrated by continuous ambulatory pH monitoring, and the improvement of pharyngeal symptoms after the use of a proton pump inhibitor.

To evaluate the regional differences in the stereometric parameters of optic nerve head in primary open angle glaucoma, we retrieved rim area, disc area, cup volume/disc area, and maximum depth in 6 predefined segements using mean topography measured with Heidelberg Retina Tomograph. Eleven eyes from 11 primary open angle glaucoma patients, whose mean defect in Humphrey C30-2 visual field was -4.2 +/- 2.6dB and intraocular pressure was 18.7 +/- 3.2mmHg, were enrolled in this study. The values of rim area/disc area were significantly different between segments(p<0.05), and increased in the order of temporal. temporoinferior, temporosuperior, nasal nasosuperior, and nasoinferior segment. The values of cup volume/disc area were also significantly different between segments(p<0.05), and decreased in the order of temporoinferior, temporosuperior, temporal, nasosuperior, nasal, and nasoinferior segment. However, the values of maximum depth were not significantly different between segments. These results suggest that optic nerve head damage in primary open angle glaucoma may be different according to the region.

Telomerase is a ribonucleoprotein that synthesizes telomere repeats. It has been reported that activation of telomerase was associtated with immortalization, proliferative activity and carcinogenesis. Recently, telomerase activity has been extensively studied in many kinds of malignant tumors for clinical diagnostic and/or prognostic utilities. In neuroblastoma, breast carcinoma,gastric carcinoma, non-small cell lung carcinoma, close relationship has been reported between high telomerase activity and lymph node metastasis, tumor aggressiveness and poor prognosis. The purpose of this study is to to investigate the clinical implication of telomerase activity assay as an adjunctive factor in decision-making on neck node management, speedy pre-operative judging on histologic malignancy grading. Thus we performed semi-quantitative assay of telomerase activity using Telomerase PCR ELISA kit(Boeringer Manheim , Germany) and evaluated correlation between telomerase activity and tumor size, neck node metastasis, Anneroth malignancy score and influence of pre-operative chemotherapy on its activity in 27 cases of oral squamous cell carcinomas and 18 cases of normal oral epithelium. Also, correlation between telomerase activities and PCNA indices was evaluated. The results were obtained as follows: 1. The telomerase activities were detected in 24 specimens out of 27 oral squamous cell carcinoma specimens (88.9%) and in 5 specimens out of 18 normal oral epithelium specimens (27.8%). The mean value of telomerase activities was 0.9793+/-0.3428 in 24 oral squamous cell carcinoma specimens and 0.4855+/-0.1117 in 5 normal oral epithelium specimens. The positivity rate and mean value of telomerase activities in oral squamous cell carcinoma specimens were significantly higher than those of normal oral epithelium specimens (p<0.05). 2. There was no significant correlation between total Anneroth malignancy score and telomerase activity (p>0.05), but points of mitosis index and depth of invasion were significantly correlated with telomerase activities (p<0.05). 3. The positive immunohistochemical staining for PCNA(proliferating cell nuclear antigen) was observed in 26 specimens out of 27 oral squamous cell carcinoma specimens and mean value of PCNA indices of 26 specimens was 53.67+/-26.46. PCNA indices were significantly correlated with telomerase activities (p<0.05). 4. The mean value of telomerase activities was significantly higher in pathologic T3/T4 group than in T1/T2 group (p<0.01). There was no significant difference of mean value of telomerase activities between pathologic neck node positive group and negative group (p> 0.05). Pre-operative chemotherapy significantly lowered the telomerase activities (p<0.05). The above results suggested telomerase activity could be used as diagnostic marker and adjunctive parameter for judging on histologic malignancy in oral squamous cell carcinoma.
